2.4.2 Debug Connector Pinouts

The below tables Table 2-5 and Table 2-6 describe the two AEC breakout/debug headers. These headers provide a convenient location to probe all of the AEC signals used on this design and most of the unused AEC signals as well.

Direction of signals are relative to baseboard EVM.

  • I - used as input to baseboard EVM
  • O - used as output from baseboard EVM
  • IO - used as either input/output baseboard EVM
  • PWR - power
  • GND - ground return
  • X - unused on this design
